If you're a devoted fan of "Merlin," you might just recognize the prop in the photo above. If you don't, I can help--and offer you the opportunity to own it. It's a "competitor certificate" that explains the holder has been invited by King Uther Pendragon (Anthony Head) to compete in the Decennial Tournament in Camelot, which is held once every decade.

The certificate appeared in "The Sorcerer's Shadow," the 11th episode of Season 3, in which Gilli, a young warlock played by Harry Melling (Dudley Dursley in the "Harry Potter" films), entered the Decennial Tournament in Camelot. Despite the risk of his own excecution, he used magic to increase his chance of victory.

The producers of "Merlin" have made this prop available to fans, and if you want the chance to have it in your collection of cool things, you'll have to "like" my Show Patrol Facebook page this week. On Friday, I'll ask a trivia question and the first to answer correctly gets it. Any fan, anywhere in the world.

Syfy debuts new episodes of the fifth and final season of "Merlin" at 9 p.m. CT Fridays. Check back here each week for a preview of the new episodes.

Here's a little more info about the Decennial Tournament in "The Sorcerer's Shadow": The Decennial Tournament is a tradition as old as Camelot itself. The tournament is held once every decade and is open to all comers, both high and low born. All matter of weapons are allowed and the only rule seems to be that there are no rules. It's a dangerous undertaking but for the prize of a 100 gold pieces many are willing to risk life and limb. Uther Pendragon has won this tournament three decades in a row. It also is implied by Uther that by winning the tournament years ago, he became king.
